Size and Sound back

[pianoman]

Hi Richard the ,
	The stopper in organ pipes perform the function of doubling the pitch.  An
8' pipe speaks at the pitch of a 16'.  It also changes the harmonic
characteristics of the tone.  Adding pipes coming out of the top of the
upright would do nothing like this.
